The Arrow-Lock Sheet Lining System is designed specifically to provide rehabilitation for corroded, but structurally sound, concrete structures such as manholes, lift stations, digesters, primary effluent channels, sludge wet wells, primary sedimentation tanks, headworks and other such areas.

The Arrow-Lock Sheet Lining System is designed specifically to provide rehabilitation for corroded, but structurally sound, concrete structures such as manholes, lift stations, digesters, primary effluent channels, sludge wet wells, primary sedimentation tanks, headworks and other such areas.

The Arrow-Lock Sheet Lining System uses two distinct products to achieve its results: Arrow-Lock Sheet Lining (like T-Lock, but with arrow-ribs instead of T-ribs) and Arrow-Lock Mastic
No. 9912, a two-part epoxy mastic and mastic primer used to mechanically lock the lining to the concrete substrate.

Like T-Lock, the Arrow-Lock Sheet Lining System provides a continuous, virtually impervious, plastic lining to protect concrete against hydrogen sulfide and other sewer gases, acids, alkalis and salts.

The Arrow-Lock Sheet is made from specially formulated polyvinyl chloride resins extruded under high temperature and pressure to form an extremely dense and impervious liner. The protruding, arrow-shaped ribs mechanically lock the lining to the Arrow-Lock Mastic.

The Arrow-Lock Mastic is a 2:1 epoxy gel for filling voids and bonding to properly prepared damp or dry concrete substrates. Although the material bonds tightly to concrete, it is not designed to provide an adhesive bond to the liner which is beneficial since it allows ground water seepage, if it occurs, to drain away without damaging the lining. Instead, Arrow-Lock Mastic flows around the lining’s arrow-ribs and, after it cures, mechanically locks the lining permanently into place. 713.375.3700, nov.com/ameron
